Introduction 

This manual is intended to assist an installer with the installation and commissioning of the 

eTower lithium iron phosphate (LiFePO4) energy storage modules. This document is not 

intended to provide detailed information of the inner workings of eTower that is not 

relevant to a person that is performing the installation and final commissioning. 

Supplementary information relating to programming of the built-in battery management 

system for non-standard inverter interfaces is available to approved integrators directly 

from Freedom Won.  
This manual does not attempt to cover all the details pertaining to the setup of third-party 

equipment in relation to the interface and necessary functionality to work with the eTower. 

Freedom Won however is available at the contact details on page one to provide direct 

support that specifically relates to the battery interfacing with supported third-party 

inverter brands.

Product Description 

The eTower range presently includes only the e5000 module, which has been designed 

specifically for enabling small economical storage solutions that can be upgraded 

conveniently and cost effectively over time.  
The product 

includes all accessories required to enable fast and convenient installation

Although rack mounting is possible, the modules are primarily designed for easy stacking 

into a tower through the inclusion of a plastic moulded pedestal that is placed underneath 

each module in the tower. Further convenience is offered through the inclusion of the 

required communication and power cables along with module connecting busbars.  
The eTower is designed primarily for systems that need to start with 5kWh initially with a 

view to growing the storage capacity over time in 5kWh increments up to 20kWh.  
For designs that require 10kWh or more initially the Freedom LiTE Home and Business range 

may be a preferred solution depending on customer preferences and needs.
